HORSE-COLLAR-BLOCKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 701,880, datedFune 10,i902. Application filedDacember 2, 1901. Serial No. 84,319. (No modelbination hereinafter described and claimed.

In the accompanying drawings, forming part of this specificatiom'Figurel is a front elevation of myimproved machine. "Fig. 2 is arear'elevation of the same. Fig. 3 is a side elevation. Fig. 4 is a top viewof the upper blocking member. Fig. 5 is a longitudinal vertical sectionof my improved machine with the parts in closed or blocking position.Fig.

6 is a view of the clamping-arms closed. Fig. 7 is a longitudinalsection of my machine with Fig. 8 is aview of the clamping-arms open.Fig. 9. is a vertical cross-section through the blocking members,clamping-arms, andadjacent parts, showing the parts inopen position.Fig. 10 is a similar View with the parts closed. Fig. 11 is a bottomviewof the'supportingand operatin g mechanism of the clam ping-arms, andFig. 12 is a similar View to Fig. 10 with a collar in position.

In the drawings, A represents the framework of the machine. k

B represents the lower block member, around which the collar is placed.The block member B is mounted upon the cross-arms 2, which rest upon thecoil-springs 3, surrounding the posts 4, which extend downwardly fromthe framework of the machine. Upon the opposite sides of the member B isa pair of clamping-armsO. The rear end of each of the arms 0 is providedwith a pin 5, passing through the outwardly and forwardly directed slot6 in the framework. The forward end of each clampin'g arm O is'connectedto the adjacent cam 7 by apin 8 passing through the intermediate-bracket9. The cam 7 and bracket 9 are supported in the framework by means ofthe pivot 10. Each of the cams 7 27 is pivoted to the slide-rod 26.

is provided with teeth 11, arranged oppositely from the pin 8 andadapted to intermesh with the adjacent worm-gear 12 upon thehorizontalshaft 13, which shaft has journal-support in the fram'eworkof themachihe,-as shown in Fig. 11. 7 Upon the endof' the shaft 13 is mounteda beveled gear 14,-intermeshing with a beveled pinion 15, carried'by'the upright shaft 16, which upright shaft has journalbearings 17 onthe frame of the machine. Upon the lower end of the shaft16 is mountSplined on the horigears19 and 20. The beveled gears 19 and 20 areprovided with anuularly-grooved hubs 22' and23, respectively, and arms24 and 25 on a slide-rod 26 ride, respectively, in the groovesinthe'hubs. A shifting lever-arm The leverarm-27 has fulcrum-support 28 uponthe'bed of the machine. either the gear 19 or 20 will be thrown intoengagement with the gear 18, thus actuating the; shaft 13 to either openor close the clamping-arms O throughthe medium of the cams 7. When theclamping-'arm sare opened and carried forward, as shown in Fig. 8, bythe turning of the cam 7, the rear ends will move Having forward andoutward in the slots 6. pivotal support upon the'framework at the rearof the clamping-arms Care the dogs 29. When the clamping-farms stand inclosed positi'onpas shown inFig. 6, the outer ends of the dogs 29 bearagainstthe sides of the clamping-arms. M

30 represents a lever having pivotal support 31 in the rear of theframework. The upper, end of the lever 30 extends upward in frontv ofthe inner ends of the dogs 29, as shown in Fig. 5, and a strip 32,connected with the lever 30, stands upon'tlie opposite sides of thedogs. Slidably supportedin; the lower end of the lever 30 istheanti'frictionroller 33, adapted to bear against the cam 34, carriedby theshaft 35. Aspring'36is secured to the lever 30 and bears againstthe spindle of the antifriction-roller 33. Mounted upon the shaft is agear-wheel 37, intermeshing with a, pinion 38, mounted upon By actuatingthe lever 27 a shaft 39. Also mounted upon the shaft 39 is a gear-wheel40, intermeshing with a pinion sll, mounted upon the shaft 42. Thepulley 43, loosely mounted upon the shaft 42, is suitably connected witha source of power, and a suitable clutch mechanism 44 is provided forthrowing the pulley 43 into and out of engagement with the shaft 42.

D represents the upper block member, supported upon the vertical shaft45, slidable endwise in suitable bearings 46. The member D is providedwith a rotatable hub 47, held to coincident vertical movement with saidmember and threaded upon the upper end of the shaft 45, anadjusting-wheel I8.

being provided, bymeans of-which the height of the block member isadjusted. Posts 49 project downwardly from the outer edge of the blockmember and extend movably into the openings 50 in the lower member B,retaining the block member in alinement vertically. Theoutwardly-projecting flange 51 of the upper block member is shapedto.fit over the belly of the collar, as hereinafter set forth. The upperblock member is actuated by the toggle-arms 52 and 53. The upper ends ofthe arms 52 are pivoted on stud-pins 54c, fixed in die E and which passthrough arms 52 and extend into vertical slots therefor in the frameworkof the machine, and the lower ends of the arms 53 are pivotallyconnected with the yoke 55, adjustable on the shaft 45. The pins 56,pivoting together the toggle-arms 52 and 53, are connected by theeccentric-rods 57 with the straps of the eccentrics 58, the eccentricsbeing mounted upon the shaft 35.

Between the block member B and the surrounding framework of the machineis arranged the die E, supported upon the pins 54, as shown in Figs. 9and 10.

In operation the parts are caused to assume the open position shown inFigs. 7and 9. The collar is then placed around the lower block B, withthe rim resting upon the die E. By actuating the lever 27 theclamping-arms are then closed through the medium of its operatingmechanism hereinbefore described. As the clamping-arms are closed theyare pressed closely into the hame-groove. The clutch mechanism 44 thenbeing actuated, the operating mechanism for the togglearms 52 and 53will be thrown into action. The movement of the toggle-arms will firstraise the die E, pressing the rim of the collar between the die and theclamping-arms C. The upward movement of the die will be limited by themovement of the pins 54: in the openings in the framework of the machine. The continued movement of the toggle-arms will lower the upperblock member D into the position shown in Fig. 10, thus pressing andshaping the belly of the collar between the flange of the upper blockmemher and the clamping-arms O. The parts are intended to be left in theposition shown in Fig. 12 until the collar is set. By adjusting theheight of the upper block member upon the shaft 45 the amount ofpressure applied to the collar may be varied.

By referring to Figs. 1, 2, and 3 it will be seen that one of theadvantages of my construction is the ability of coupling a number offrames, the side of one frame constituting one side of the next. Amongthe further advantages of my construction are the independent pressingof the rim and belly against the interposed clamping-arms and the adjustability of the block members. Another ad vantage is the compensatingfor different sizes of collars, caused by the yielding of the spring 36to allow separation of the clampingarms.
